The application of different types of compensation air damper compensation, by the environmental impact of the surrounding magnetic field, but due to the complexity of the assembly process more used in production of small, high precision automatic levelizer. Cross-type magnetic damping compensator, the assembly process is simple, part accuracy requirements are not very demanding, low cost dsz2 levelizer, but after the inversion for the compensation if subjected to more intense after the shock, since the hanging wire bending deformation caused by the failure probability compensation very high; so this compensation is widely used in middle and low auto levelizer, but is rarely applied in high-end equipment among. Desktop magnetic damping compensator Level, the assembly process is relatively complex, component requirements are relatively high, the cost is relatively high, but because of the earthquake than other compensation, and more are applied in high-end automatic levelizer. Notes 1, Level mounted to a tripod center must be immediately connected to screw tightened to prevent the instrument from the tripod fall break. 2. After unpacking the first to see the instrument is placed inside the case and accessory case, remove the instrument with both hands and shut it behind me. 3, the instrument should not overtighten Level knob purposes, fretting spiral can only use moderate position, not too far. 4. To release the level of braking equipment packing spiral, try closing the cover, not too much force, crushing equipment.
